Default .30Cal Lot FN 58f/57

I just acquired a box of ammo marked .30 cal Ball BDR,
Lot FN 58f/57. All the cases I looked at had headstamp of FN 57.
It is in cloth bandoleers with striper clips. The stripper clips are very bright almost a chrome color.They are Berdan primed.
The box has a stencil that says "Repackaged".
My reading says that any thing FN 58 or later should be non-corrosive, however with all the headstamps saying FN 57, I should assume this stuff is corrosive, correct?

Thanks,
Bill

Could be non-corrosive. Test by firing primer onto bright steel and observing residue over next week. Humidity accelerates the process. I have tested FN 55 and found it to be non-corrosive. Non-corrosive, the black spot stays black. Corrosive, rust forms. An old lawn mower blade works great, or any piece of steel bar stock. Hit it with wire brush or angle grinder to brighten it first.
